Evolution in the brain, Evolution in the Mind: John Hughlings Jackson and the Origins of Psychoanalysis (and of Neuropsychoanalysis) Abstract: This article first aims to demonstrate the different ways the work of the English Neurologist John Hughlings Jackson has influenced Freud. It will be argued that these can be summarised in five points. It is further argued that the framework proposed by Jackson continued to be pursued by 20th century neuroscientists such as Papez, MacLean and Panksepp into tripartite hierarchical evolutionary models. Finally, the account presented here will shed some light on the similarities encountered by neuropsychoanalytic researchers between contemporary accounts of the anatomy and physiology of the nervous systems on the one hand, and of Freudian models of the mind at the other. These, I will demonstrate, are more than similarities. They have a historical underpinning to them, as both accounts originate from one common source: John Hughlings Jackson’s tripartite evolutionary hierarchic view of the brain. Word count: 10,177 1 As new methodologies for the neural sciences were developed throughout the 20 th century, thus allowing researchers to study the underlying physiology of complex phenomena that were previously almost exclusively studied by psychoanalysis, a branch of researchers with a psychoanalytic or psychodynamic theoretical background have progressively developed an interest in these methods as a means of testing their own theories. This is illustrated by the increasing popularity of the neuropsychoanalytic movement (for a review, see Fotopoulou et al. 2013; Mancia 2006; Leuzinger-Bohleber et al. 1998), as well as by a growing body of clinical and conceptual studies that uses neuroscientific methods as to test psychoanalytic theories 1. The interdisciplinary enterprise counts today, in fact, with two journals solely devoted to the field 2, as well with an international society. However fruitful this interdisciplinary project proves to be, it has also brought much conceptual confusion, as it would be expected from disciplines that developed almost completely independently for over a century. This has generated extensive debate – sometimes of a heated nature (Cf. Blass & Carmeli 2015; Blass & Carmeli 2007; Yovell et al. 2015; Mancia 2007; Pugh 2007; Ramus 2013). Possibly driven as a means of clarifying its epistemological framework, the interest in the origins of psychoanalysis, and particularly in Freud’s scientific beginnings and early influences, has again become the focus of historical research in recent years. One such example is found in the work of the founder of the neuropsychoanalytic movement, the neuropsychologist and psychoanalyst Mark Solms. In his initial writings, Solms first delved into the prehistory of psychoanalysis (Solms, 2000a, 1 The Neuropsychoanalysis Association maintains a long and updated list of studies in https://npsa- association.org/education-training/suggested-reading/ 2 ‘Neuropsychoanalysis’ and ‘Frontiers in Psychoanalysis and Neurosciences’ 2 2000b, Solms & Saling, 1986, 1990) before engaging into work aiming to combine both fields (Solms, 2014; Solms & Panksepp, 2012; Solms & Turnbull, 2002; Zellner, Watt, Solms, & Panksepp, 2011). In his words: I want first of all to take you backward into history, to trace the origins of psychoanalysis to a particular branch of neuroscience, and to show you how the psychoanalytic method grew out of that branch; then I want to trace subsequent developments in that field to show you that it still remains the natural point of contact between our two disciplines. In the process, I hope to be able to demonstrate that – just as we find in our clinical work – a problem, which seems insolubly complex in its present, mature form, frequently turns out to have a relatively simple structure when one traces it back to its origins (Solms 2001 p.180). We see here an instance where the historiographic work in psychoanalysis serves as a preliminary stage in a determinate project, i.e., that of demonstrating that 1) psychoanalytic ideas (in particular the models of the mind) have their origins in the neurosciences and are still influenced by them; 2) that because of this common origin, shared ideas in the disciplines developed in parallel; and foremost 3) that because of this parallel development, the disciplines can be joint together again in the present. Solms is not alone in this enterprise. Another notable example is found in the work of George Makari. As the historian Patricia Cotti argued in her extensive review of Makari’s book (2008) for this journal, ‘history, depending on how it is told, can permit or not the realization of the scientific potential of psychoanalysis’ (Cotti 2012 p.145). 3 In this line, both Makari and Solms can be thought as ‘developing a new historiography, [which] repositions psychoanalysis among the sciences’ (ibid., p.134). The present paper may be understood as in line with this particular approach to the history of psychoanalysis as regards the two first points, while leaving the third one as an open-question. Amongst the early influences, the work of one author seem to have raised particular interest in scholars, partly due to the wide influence of his constructs in central psychoanalytic ideas, and partly due to his influence being still relatively unexplored. John Hughlings Jackson (1835-1911), ‘the father of English neurology’ (Critchley & Critchley, 1998), was a talented neurologist and neuropathologist who is today best remembered for his contributions to the understanding of epilepsy and for co- founding Brain: A Journal of Neurology , still today one of the most influential in the field . His name is also attached to the description of a characteristic symptom in focal motor seizures (“the Jacksonian March”) and to a type of psychomotor seizure of the temporal lobe (“Jacksonian Seizure”). But more than a neurologist, Jackson demonstrated in his writings a talent for philosophy – a field for which he almost abandoned medicine early in his career (Hutchinson, 1911) – and in particular epistemology and philosophy of mind (c.f. Jacyna, 2011; Smith, 1982). Scholars have collectively singled out five main areas where Jackson has influenced Freud. First, it has provided Freud, while still a researcher in neurology, with a dynamic framework of the functioning of the nervous system that sharply contrasted with the Austro-German School of which he was originally affiliated, and which was consistent with his empirical findings (Solms & Saling, 1986, 1990). Secondly, Jackson provided Freud with a theory on the relation between mind and brain that would prove capital in his distanciation from neurology and development of a pure 4 psychology (Fullinwider, 1983; Makari, 2008; Solms & Saling, 1986; Stengel, 1963). Further on, the hierarchy of the nervous system proposed by Jackson, based on Spencerian ideas, would also provide Freud with the central tenets for his hierarchical models of the mind (both the topic and the structural) (Modell, 2000; Wiest, 2012). Freud’s theories on regression and repression also bear many similarities with Jackson’s, and can be understood as a consequence of this hierarchical perspective on brain evolution (Fullinwider, 1983; S. W. Jackson, 1969; Linn, 1960; Stengel, 1963; Sulloway, 1979, pp. 270–2). Lastly, in a previous paper, I also explored the influence of Spencerian and Jacksonian ideas on evolution in Freud’s social theories (Niro Nascimento, in press). Comment [NL1]: Insert Jacques Nassif: ‘penser Charcot avec Jackson, et Jackson en function the Charcot’. Although the collective effort of scholars demonstrates the relevance of Jacksonian ideas for Freud, to my best knowledge, all contributions so far have focused on only one or two of these points and no work has yet collected them all together. Given the pivotal role played by the English neurologist, it is an important and valuable task to aggregate and summarise these findings so that we can better evaluate not only the historical but also the contemporary relevance of his work for psychoanalysis, and in particular for a better understanding of the neuropsychoanalytic project, which I will try to demonstrate in the second half of the paper. However, in order to properly grasp the influence Hughlings Jackson’s work had for psychoanalysis, we must first begin by revisiting Freud’s medical education so as to contextualize the problems he was addressing at the time. 5 Freud’s Medical Education After having worked in the physiological laboratory of Ernst Brücke (1819-1892) for almost seven years, between 1876 and 1882, a period also deeply influential to his psychoanalytical work but outside of the scope of this paper (cf. Amacher, 1965; Bernfeld, 1944, 1949), Freud was advised by Brücke to give up his hopes in attaining a salaried position at the department and move over to a private clinical practice so as to earn a living and be able to fulfil his long desire to marry his fiancée (Freud, 1925). Following this advice, he joined the General Hospital of Vienna in 1882 initially as an Aspirant (an unsalaried position). He completed internships in surgery, internal medicine (under Hermann Nothnagel), psychiatry (Theodor Meynert), dermatology (Hermann von Zeissl), and neurology (Franz Scholz), being promoted in 1883 to Sekundarartzt in the psychiatric department led by Theodor Meynert (1833- 1892), where he worked until 1886 (Guenther, 2012). Under Meynert, Freud would study the human nervous system – he had so far with Brücke studied solely lower vertebrates (Freud, 1877a, 1877b, 1878) –, and in particularly the spinal cord and medulla oblongata (Freud, 1884, 1886a, 1886b, 1888; Freud & Ossipowit, 1886). It is worth noting that at the turn of the century the fields of neurology and psychiatry hadn’t yet taken on the shape by which we know them today. Until the eighteenth century specialization in medicine was poorly perceived by both the general public and medical establishment, and didn’t start taking place until the early nineteenth century as the number of general practitioners increased and doctors had to find a way of standing out from the competition (Scull 2011, 72).
